Yball whom it may concern: Be it known that I, RIoHAno CAREWEL'L, a citizen of the United States, and residing at Brooklyn, in the county of Kings and State of New; York, have invented certain new and useful Improvements in Gas Supply and Regulating Valves for Inverted Gas-Burners, .of which the following is a specification, .such as will enable 'those skilled theart tov whieh it jappertains to make and use-the same. 5 l This invention relates towhat are known as inverted gas burners orregenerativegas burners in which the gas is heated before Being, burned and in which anincandescing mantle is employed, and the object thereof is to provide'improved meansifor regulating the supplyjof gas to burners of this class whereby the supply may be regulated without causing the burner to smoke, l The invention is fully disclosed in the following specification, of 'whichthe accomforms a part, in which the p nying-dra v n s a separate parts 0 my lmprovement are designated by suitable reference characters in" each of the views, and-in which Figure 1 is a side view of a burner of, the class specified provided with jmy improveman a;v i

2 a vertical sectional detail. thereof a show ng, e valv K n, cross s e Fig; 3a partial horizontal sectional view en. the lin 3+3 f ga I @Fig. 4 a modification of the construction shown in Fig. 2. I y I I In the drawing' forming part of this specification, I have shown at aaburner of the class specified in which the incandescing mantle b is indicatedin dotted lines, and the burner is provided with the usual canopy or shade c, andis connected with the usual pipe 0? in the bottomportionof which are formed slots oland on the bottomlportion of the pipe cl; is placed theusual rota-i table sleeve d having slots oltand provided with a milled collar (1 by which it may be rotated"and this 1 construction forms the usual air register device for burnersofthis class. J

In connection with' the pipe 11, I employ a tubular coupling 6 which is screwed into the, pipe 03 and provided at its lower end with a reduced lower end portion, an axial gas port or passa e e controlled by a valve e*, and the va ve e is provided with a transverse port the chain. it to the left extension e having, infits f,

e which is tapered as shown in Fig. 2, or larger at one end than at the other,a.nd the upper end of the port 6 is also larger than the lower end thereof. 9 a The coupling 6 is screwed onto the main gas supply in the usual manner, andthe larger end of the valve e is provided with a head 6 through whichis passed an arm 9, the end portions of which are of equal length and provided with suspended chains or other flexible devices it. T i 3 The smaller end of the valve 6 is provided with a disk or collar 2" held in placeby. a screw 9 passed therethroughand into the valve, and said collar ordisk isprovided with two projectingteeth and i separated by an arc of approximatelyninety de grees, and the piped is providedwith a lug or projection j through which passed. a setscrew 7c, and the set screw Zaoperatesin connection with the tooth 71 while the tooth 2'? operates in connection with the lug or projection 7' to limitthe rotationof the valve 6 and said. valve is operated bythe arm 9 in the usual manner.

Lamps 01' burners e f the classun'dercom sideration are usually provided with two valves oneserving as a regulator and the other as a full supply and cut-offland this construction forms between said'valves a gas chamber and the variationof gas pressure in the operation of the 1 said valves causes the burner to smokeat times and one of the objects, of this iInprovement is to overcome this objection, and the operation of the improved construction hereindescribed will be readily understood fromfthe rforego ing description whentaken in -connection with the accompanying"drawing and the following-statement thereof. 7

The position of the valve and the disk or collar 2' as shown in Fig. l is theclosed position, as indicated in Fig; 2,and' by drawing downwardly into the position indicated in dotted lines, which operation movesfthe arm 9 into the position shown in dotted lines, the valve-e will be rotated as well as the disk'or collar and the projecting tooth i? will strike the end of the screw k which limits themovementof said valve and,in Fig. 2, I have indicated in dottedlines the positionof the port .65 in said valve, which corresponds with the position of the disk or collar 2', as indicated in dotted lines in Fig. 1.

It will be understood that the screw 7:

may be withdrawn to fully open the port e in the valve 6*, or said screw may be manipulated to decrease the size of the opening of the port 0 in connection with the port 0 in the reduced extension 6 of the coupling e.

- In Fig. 1 of thedrawing I have shown the usual pilot light pipe m which is connected with the tubular coupling a and passes downwardly and the end m thereof communicates with the burner, or the incandescing-mantle b in the usual manner and passed through the coupling a on the opposite side of the connection ofthe pipe on therewith is the usual adjusting screw it which operat,es-. in connection with said pilot pipe m vto govern the: supply of gas through said pipe. This construction. is shown in Fig. 1 only for thereason that the said pilot light forms no partof my invention more than in the fact that my improved valve mechanism is particularly designed for burners employing the pilot light attachment, but it will be understood that my invention is not necessarily limited to this feature nor to the specific means for governing themovements of the valve 0* 1n one direction, to increase or decrease the size of the port or passage 6 The parts e and cl form an air and gas mixing chamber 0 intowhichthe gas is dis-. charged andin which the gas and air are mingl d: in the usual manner, and, in Fig.

llhaveshownz another form of construction in which the valve 6 instead of being provided.v with. a. transverse and, tapered port or 'passageis provided with a largecylindrical port or passage. 6", the discharge end of which is closed. by a thin web- 6 in which is a supplemental port or passage 6 which is adapted toregister with the port or passage 0 and theport or passage 69 is of greater dimensions than the port or passage 6 and with this construction of the valve, and with that shown in Figs, 2 and 3, the gas will be discharged in a direct, line centrally through the port orpassage and not in a'flaring or lateral direction, and thiswill prevent wavering or flickering ofthe flame of the burner. c

Having fully described my invention, what I claim as new and desire to secure by Letters Patent, is

1. In a device of the class described, a pipe coupling, provided with. a reduced extension having an axial port,a pipe screwed onto saidv coupling andfinclosing, the reduced extension thereof, a valve passed through said pipe and through the extension; of said coupling and adaptedt'o control said port, said valve being provided at one end with (topics 0mm. patent mite obtained to:

said pipe being provided adjacent to said collar with a lug or projection in connection with which one of saiuteeth operates, and a set screw passed through said lug or proj ection and adapted to operate in connection with the other of said teeth.

2; In a device of the class described, a pipe coupling provided with as reduced extension having an axial port, a pipe screwed onto said coupling -and.inclosing the reduced extension thereof, a valve passed through said pipeand through the extension of said coupling and adapted tocontrol said port, said valve being provided atone end with a transverse arm and atthe other end with a collar having spaced projectingteeth, and said pipe being provided adjacent to said collar with a lug or projection inconnection with which one of said teeth operates, and a setscrew passed through said lug or pro.- jection and adapted to operate in connection with the other of said teeth, said valve being provided with a transverse port which is largerat one end than atthe other and the port in the extension of the pipe coupling being also larger at one end than at. the other. I

3. In a device of theclass described, a gas supply pipethe lower end of. which: is in closed. in a supplemental pipe provided with anair: register device and Within which is a mixing chamber, said, lower end of the first namedpipe being provided with, an axial port the outlet oi which issmaller than the inlet, a valve ,passed transversely through the said lower end of the first named. pipe closely adjacent to the outlet of the axial port and spacing the inlet of said axial port from the outlet and-through which gas; is discharged into the ,mixing member, said, valve, being provided; with a, transverse port or passage the discharge end of which isclosed, by a thin'web having a small port adapted toregister with, the outlet oi the axial port, for guiding gascentrally to the mixing chamber, and the outlet of the port orpassage. in the valve being larger than theoutl'et of said axial port or passage into the mixing chamber,

In testimony that I claim, the foregoing as my invention I have signed my namein presence. of the subscribing witnesses this,
